I tried mounting the 280mm in the top of my case. The radiator got stuck and scratched it a bit when i managed to get it out.
Returned and ended up with a 50% return cost so that was a lovely £50 lesson!
Maybe experiment finding your good cores, set them to lower (e.g. -5 on curve) and maybe try chsnging the PBO limits. Doing so reduces temps so boost has more to play with
Think i'll give this a go later, can't help but think my motherboard is holding me back though, we have pretty similar systems and i can't seem to get my teamgroup to hit 3800 cl14 without errors so thinking i may have problems ocing the cpu as well also.
Any suggestions on how i'd go about finding which are my good cores?
